Coffee Consumption and Type 2 Diabetes Risk Reduction

Researchers in Germany investigated the association between coffee consumption and risk for having a heart attack or stroke or developing cancer or type 2 diabetes. Their results were published in the American Journal of Clinical Nutrition.

This study used data from more than 40,000 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC)—Germany study. Coffee consumption was measured via a self-administered questionnaire, and the study had a follow-up period of 8.9 years.

There was no association between coffee consumption and increased risk for any of the investigated diseases. Interestingly, however, investigators found that those who drank 4 or more cups a day of either caffeinated or decaffeinated coffee had a 23% and 30% risk reduction in the development of type 2 diabetes, respectively, compared with those who drank less than 1 cup a day.
